Problems solved by technology

[0004] However, when the microstrip antenna is integrated into an integrated circuit, there will be electromagnetic compatibility problems, which will reduce the quality of communication. Therefore, it is necessary to add a filtering structure to suppress harmonics, but the general filtering structure may cause problems in the frequency reconfigurable When the antenna works at a low frequency, the filter structure to remove low frequency harmonics may cause the antenna to fail to work properly when it switches to a high frequency working state

Abstract

The invention relates to a dual-polarization three-band frequency reconfigurable antenna with a reconfigurable harmonic suppression function, which comprises an upper dielectric substrate, a lower dielectric substrate, an upper antenna reconfigurable radiation unit, a lower antenna reconfigurable radiation unit, an upper reconfigurable filtering structure and a lower reconfigurable filtering structure. Frequency reconfiguration of three bands and antenna polarization reconfiguration are realized, and meanwhile, when the antenna works in different bands, harmonic waves of each band are suppressed, and normal work of other bands is not influenced.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a dual-polarization and three-band frequency reconfigurable antenna with a reconfigurable harmonic suppression function, which can be applied to a wireless communication system. Background technique [0002] Since the 1960s, with the rapid development of modern radar and communication systems, the number of antennas required for aircraft, ships, satellites, etc. many. As a result, the weight of the platform continues to increase, and the cost of building the antennas also continues to rise. At the same time, the electromagnetic interference between the antennas is also very large, which seriously affects the normal operation of the antennas. Due to the small size and changeable functions of the reconfigurable antenna, in order to reduce the weight of the antenna loaded on the platform and reduce the cost, research institutions at home and abroad have conducted some in-depth resea...
